To wZZ' whom it may concern,.- A

Be it known that l, EDWARD H. SoorrELn, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new land useful Improvements in Brake- Hangers; and l do hereby declare the following to be a Jfull, clear, and exact description of i as will enable others skilled in the art to which it appertains to make and use the same.

.My invention has `for its object to provide animproved brake-hanger; and to this end it tions of devices hereinafter described, and defined in the claims.

The improved brake-hanger is illustrated drawings, wherein like characters indicate llke parts throughoutthe several views.

Figure 1 is a view, vation, but with some line fr as of Fig. 2, showing proved brake-han ers applied t0` sup ort a brake head and s oe from; a truckame,

principally in side eleparts sectioned on the one of my imbeam of course one .oi the parts of the truck-frame being broken away and one'of the truck-wheels being indicated in part by dotted lines. Fig. 2 is a front elevation of the mechanism shown in Fi 1, but l with the brake-shoe removed and wit one of Ii the longitudinal bars -of the truck-frame sectioned on-the line x2 x2 of Fig` 1. Fig. 3 is a section on the line x3 :r3 of Fig. 2. Fig. 4 is a `section on the line x4 of Flg. 3. Fig. 5 is a lplan view showing one corner portion of the truck-frame. Fig. 6 is a plan view showing one of the brake-heads and a portion of the brake-beam, to one end of which the said i head is rigidly attached; and Fig. 7 is a detail view in plan showing the so called thrust-sleeve of the brake-hanger.

, The numeral 1 indicates one oi the longil transvers end bars, of the 'truck-frame, which truck-frame may be of ordinary or any suitable construction.l

In Fig. 1 the curved dotted line (marked 3) l indicates the peripheralline or'iace of one of' the truck-wheels.

The numeral 4 indicates one of the brakeheads, to which is detachably secured a brakeshoe 5, shown as held thereto by a long curved key 6, passed-through perforations in the intlrlapping lug portions of the said head and s 0e.

ed thereon.

The numeral 7 indicates the compressionbar, and the numeral 8 the tension or truss rod, of the brake-beam, to each end ci' which brake-heads 4 is rigidly secured in the usual or any suitable way.

Bolted or otherwise rigidly secured on the transverse end bars 2 are brake-supporting brackets 9, only one of which is shown in the drawings. This bracket 9 is provided with an inwardly-projecting se mental bearing- Web .10, which is bifurcatef or slit at 10a, as best shown in Figs. 2 and 3, and for a purpose which will presently appear. The sections of the bifuroated segmental web 10 are strengthened by vertical ribs 10b, cast inte ral therewith and with the body ofthe brac et 9.4

The brake -head ,4 in its up er end is Jformed with an inverted 'pocketike seat 11' ens centrally segmental bearing-surface 1,3, which extends concentric to the upper portion of said pocket and extends transversely of thehead approxiimately the Width oi the said pocket.

The brake-hanger proper is composed of a headed bolt 14 and a thrust-sleeve 15, mount- At its lower end the bolt 14 is provided with a transversely-extended head 16, which in cross-section is 4cylindrical and iits the upper cylindrical bearing-surface of the pocket l1 of the brake-head. The body of the bolt works pivotally through the seat 12 of said brake-head andthrough the slit 10a of the segmental bearing-web 10 ofthe bearing-bracket 9. The semicylindrical rocker or bearin -block 17 -its and works' upon the upper cy indrical surface of the segmental bearing-web 10. The screw-threaded upper end of the bolt l14 is passed through a perforation in the central portion ol' the rocker 17 and above said rocker is provided with a pair of lock-nuts 18. The thrust-sleeve 15 is formed in its ends with transversely-extended cylindrical depressions or seats that engage one with. the lower cylindrical ortion of the web 10 and the other -with tlie cylindrical bearing surfaces or shoulders 13 on the brakehead 4.

When the nuts 18 are removed from the bolt 14 or are sufficiently loosened up thereon and when the brake-shoe is removed Above the l .pocket 11 the brake-head is formed with a IOC v wor 'ng position, as shown in the drawings,

the nuts 18 should be so set that all play between the thrust-block 15, bolt-head 16, and rocker 17 vand engaged parts of the brakehead and brake-supporting bracket will be taken'- up. It is important to here note that since 4the thrust-sleeve 15 is free to slide on the bolt 14 both the said parts are by one and the same adjustment of the nuts 18 ,drawn into friction-al enga ement with the seats and bearing-surfaces o the'brake-head and its supporting-bracket.

'The importance of being able to take up slack between the parts, so as to compensate for wear and to preventclattering, is too obi lt is evident vious to need much comment. that such adjustments may be easily and quickly accomplished in my improved brakehanger. It is also evident that the brakehead is supported so that it may freely move to carry the brake-shoe to and from contact with the wheel. It is further important to note that under the vbrake-setting action downwardly-tending forces applied to the brake-shoe from the Awheel will e resisted by the tension-bolt 14, While upwardly-tending Jforces ap lied to the brake-shoe from the wheel Wi be resisted by the thrust-sleeve. In this way the work on the two parts of the brake-hanger will be divided between them;

also, a solid or un ielding resistance under upwardly-tending orces on the brake-head isafforded.

The brake-hanger described is of simple construction, is very quickly applied in working position 'or removed therefrom, makes quick adjustments possible, and, furthermore, is exceedingly strong and durable.

It will of course be understood that the device described is capablel of modification within the scope of' my invention as herein set forth and claimed.

In the drawings the seat in the brake-head for the T-head of the tension-bolt 14 opens on the inner 'face ,of the brake-head, and the said bolt is held within its seat when the vbrake-shoe is applied to the brake-head; but 1 it will of course be understood that the bolthead seat might open at the rear face otl the i brake-head, so that the said bolt might be rel moved from working position without vre- The construction moving the brake-shoe. illustrated, however, is believed to be better than the modification suggested. i

Freni the relative functions ofthe parts, as

hereinbelore described, it must of course be obvious that what l have called the tension-bolt -1 4 may be regarded or termed the tension member of the brake-hanger and thatv what I have called the thrust-sleeve 15 might be termed the compression member of the brake-hanger. The said bolt or tension member 14 takes the strain applied y to the brake-shoe from the wheels when turning downward in' respect to the brake, and the said sleeve or compression member 14 takes the strain when the wheels are turnino upward in respect to the brake, while at all times the brake is Jfree for theirequisite pivotal actions both at the brake-slice and at the Apoint of suspension Jfrom the framebracket. It is equally true that instead of the words brake-hanger used by me to include the tension-bolt and the thrust-sleeve 'or compression member that the said two devices might be collectively termed la suspension device for brake-shoes, but it is thought that the term brake-hanger is the most appropriate and apt term for use for that purpose. Said tension-bolt 14 might also be called a suspension-link.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. The combination with a brake-head, of a brake-hanger involving a pair of parts, one of which receives end thrusts and the other tension strains, in the brake-setting action.

2. The combination with a brake-head, of a brake-hanger made up of the telescoped parts pvotally supporting said brake-head, one part being arranged toreceive vend thrusts and the other tension strains, in the brakei setting action. i 3. The combination with a brake-head and a supporting-bracket on the truck-frame, of a brake-hanger comprising a tension-bolt pivoted to said brake-head and to said supporting-bracket, and a thrust-sleeve on said bolt, between the brake-head and supportingbracket, arranged to-receive end thrusts, substantially as described. il 4. The combination with a brake-head and i a supporting-bracket said brake-head havine i an open seat formed with a slitted eyli'ndrica IIO bearing-web and said bracket having a slit- Q ted segmental beariiig-web, ot' a tension-bolt working through the slitted web of said brake-head with its laterally-expanded head working' within the seiit thereof and with its upper end working through the slitted web of said bracket, a rocker seated in the concavitv oi" t he bearing-web ol' said bracket and through which the upper end of said tension-bolt is passed, nuts on the threaded upper end. of i said tension-bolt, anda thrust-sleeve on said i tension-bolt bearing against the outer con- 1, cave surfaces of the webs of said brake-head t and bracket, subs'tantiallyas described. 1 5.
